As a priority application for Korean Patent Application No. 10-2013-0131747 filed as a date, all contents disclosed in the specification and drawings of the corresponding applications are incorporated herein by reference.
일반적으로, 이차 전지는 충전이 불가능한 일차 전지와 달리, 충방전이 가능한 전지를 의미하며, 휴대폰, 노트북 컴퓨터, 캠코더 등의 전자기기 또는 전기 자동차 등에 널리 사용되고 있다. 특히, 리튬 이차 전지는 전자 장비의 전원으로 많이 사용되는 니켈-카드뮴 전지 또는 니켈-수소 전지보다 용량이 크고, 단위 중량당 에너지 밀도가 높기 때문에 그 활용 정도가 급속도로 증가되는 추세에 있다.In general, a secondary battery, unlike a primary battery that cannot be charged, means a battery that can be charged and discharged, and is widely used in electronic devices such as mobile phones, notebook computers, camcorders, and electric vehicles. In particular, lithium secondary batteries have a larger capacity and higher energy density per unit weight than nickel-cadmium batteries or nickel-hydrogen batteries, which are widely used as power sources for electronic equipment, and thus, their utilization rates are rapidly increasing.
이러한 리튬 이차 전지는 주로 리튬계 산화물과 탄소재를 각각 양극 활물질과 음극 활물질로 사용한다. 리튬 이차 전지는, 이러한 양극 활물질과 음극 활물질이 각각 도포된 양극판과 음극판이 세퍼레이터를 사이에 두고 배치된 전극 조립체와, 전극 조립체를 전해액과 함께 밀봉 수납하는 전지 케이스를 구비한다.Such lithium secondary batteries mainly use lithium-based oxides and carbon materials as positive electrode active materials and negative electrode active materials, respectively. The lithium secondary battery includes an electrode assembly in which a positive electrode plate and a negative electrode plate coated with the positive electrode active material and the negative electrode active material are disposed with a separator interposed therebetween, and a battery case sealingly storing the electrode assembly together with the electrolyte solution.
한편, 리튬 이차 전지는 전지 케이스의 형상에 따라, 전극 조립체가 금속 캔에 내장되어 있는 캔형 이차 전지와 전극 조립체가 알루미늄 라미네이트 시트의 파우치에 내장되어 있는 파우치형 전지로 분류될 수 있다. 그리고, 캔 형 이차 전지는 다시 금속 캔의 형태에 따라 원통형 전지와 각형 전지로 분류될 수 있다.Meanwhile, the lithium secondary battery may be classified into a can type secondary battery in which an electrode assembly is embedded in a metal can and a pouch type battery in which an electrode assembly is embedded in a pouch of an aluminum laminate sheet according to the shape of a battery case. In addition, the can type secondary battery may be further classified into a cylindrical battery and a square battery according to the shape of the metal can.
전극 조립체는 양극판과 음극판 사이에 세퍼레이터를 개재시켜 권취한 젤리 롤 타입과, 양극판과 음극판 사이에 세퍼레이터를 개재시킨 전지 셀을 순차적으로 적층시킨 스택 타입 등으로 분류될 수 있다. 스택 타입의 전극 조립체는 주로 파우치형 전지에 이용되고, 젤리 롤 타입의 전극 조립체는 주로 캔 형 이차 전지에 이용된다. 특히, 이 중에서 스택 타입의 전극 조립체는 다수의 양극 및 음극 단위 셀들이 순차적으로 적층된 구조로 중량당 에너지 밀도가 높고, 각형의 형태를 얻기가 용이한 장점이 있다.The electrode assembly may be classified into a jelly roll type wound through a separator between a positive electrode plate and a negative electrode plate, and a stack type in which battery cells having a separator interposed between the positive electrode plate and the negative electrode plate are sequentially stacked. Stack type electrode assemblies are mainly used for pouch type batteries, and jelly roll type electrode assemblies are mainly used for can type secondary batteries. In particular, the stack type electrode assembly has a structure in which a plurality of anode and cathode unit cells are sequentially stacked to have a high energy density per weight, and it is easy to obtain a rectangular shape.
한편, 이와 같은 스택 타입의 전극 조립체는 양극판, 음극판 및 이러한 양극판과 음극판 사이에 개재된 세퍼레이터를 포함하는 전지 셀이 둘 이상 적층되어 제조된다. 이러한 전극 조립체가 일정한 규격으로 제조되려면, 전지 셀이 나란하게 정렬된 상태로 적층되어야 한다. 전지 셀이 제대로 정렬되지 않은 상태로 전극 조립체가 제조될 경우, 전극 조립체는 전지 케이스에 수납되지 못하게 될 수 있다. 또한, 전지 셀이 제대로 정렬되지 않은 상태로 제조된 전극 조립체는 에너지 밀도가 낮아 에너지 효율성이 떨어지는 단점이 있다.Meanwhile, the stack type electrode assembly is manufactured by stacking two or more battery cells including a positive electrode plate, a negative electrode plate, and a separator interposed between the positive electrode plate and the negative electrode plate. In order for such an electrode assembly to be manufactured to a certain specification, battery cells must be stacked in a side by side alignment. When the electrode assembly is manufactured while the battery cells are not properly aligned, the electrode assembly may not be stored in the battery case. In addition, the electrode assembly manufactured in a state where the battery cells are not properly aligned has a disadvantage of low energy efficiency and low energy efficiency.
그럼에도 불구하고, 아직까지 이러한 스택 타입의 전극 조립체를 제조하기 위해 전지 셀을 정렬하는 기술에 대한 연구가 제대로 이루어지지 않는 실정이다. Nevertheless, research on the technique of aligning battery cells to manufacture such a stack type electrode assembly has not been conducted properly.
본 발명은 상기와 같은 문제점을 인식하여 창안된 것으로서, 신속하게 전지 셀을 적층하고, 적층된 전지 셀의 정렬도를 향상시키기 위한 전지 셀 적층 지그를 제공하는 것을 목적으로 한다.The present invention has been made in view of the above problems, and an object thereof is to provide a battery cell stacking jig for quickly stacking battery cells and improving the degree of alignment of the stacked battery cells.

본 발명에 의하면, 스택 타입의 전극 조립체를 제조하는데 사용되는 전지 셀이 정확하게 정렬된 상태로 적층될 수 있다. 따라서, 전지 셀의 정렬도가 향상되고 이로 인해 전극 조립체의 에너지 밀도가 증가할 수 있다.

The battery cell alignment unit 200 may include a first block 210 and a second block 220 so that the battery cells 10 may be aligned side by side. Here, the first block 210 and the second block 220 is mounted on the seating portion 100, as shown in FIG. In addition, the first block 210 and the second block 220 may be spaced apart by a predetermined distance.

Doing. As such, the first block 210 and the second block 220 may be implemented to be movable on the seating part 100.
한편, 도 1에 도시된 실시예에서는 제1블록(210) 및 제2블록(220)이 모두 이동가능하도록 구현되어 있으나, 본 발명이 반드시 이러한 실시예에 한정되는 것은 아니며 제1블록(210) 및 제2블록(220) 중 어느 하나의 블록만 이동가능하도록 구현될 수도 있음은 물론이다. 또한, 도 1에 도시된 본 발명의 일 실시예에 따른 전지 셀 적층 지그는, 가이드레일(r)과 플레이트(p)를 구비하고, 이러한 가이드레일(r)과 플레이트(p)를 이용하여 제1블록(210) 및 제2블록(220)이 안착부(100) 상에서 이동할 수 있도록 구현되어 있으나, 본 발명이 반드시 이러한 구현예에 한정되는 것은 아니다.Meanwhile, in the embodiment illustrated in FIG. 1, both the first block 210 and the second block 220 are implemented to be movable, but the present invention is not necessarily limited to such an embodiment, and the first block 210 may be used. And it may be implemented that only one of the second block 220 is movable. In addition, the battery cell stacking jig according to the exemplary embodiment of the present invention illustrated in FIG. 1 includes a guide rail r and a plate p, and is formed using the guide rail r and the plate p. Although the first block 210 and the second block 220 are implemented to move on the seating part 100, the present invention is not necessarily limited to this embodiment.
본 발명의 일 실시예에 따르면, 상기 전지 셀 정렬부(200)의 제1블록(210) 및 제2블록(220) 중 적어도 어느 하나는 안착부(100) 상에서 좌우 방향으로 이동할 수 있고, 다른 실시예에 따르면, 제1블록(210) 및 제2블록(220) 중 적어도 어느 하나는 안착부(100) 상에서 전후 방향으로 이동할 수 있으며, 또 다른 실시예에 따르면, 도 1의 실시예와 마찬가지로 제1블록(210) 및 제2블록(220) 중 적어도 어느 하나가 안착부(100) 상에서 전후 방향 및 좌우 방향으로 이동할 수도 있다. According to an embodiment of the present invention, at least one of the first block 210 and the second block 220 of the battery cell alignment unit 200 may move in the left and right directions on the seating unit 100, and the other According to an embodiment, at least one of the first block 210 and the second block 220 may move in the front-rear direction on the seating part 100, and according to another embodiment, as in the embodiment of FIG. 1.

It may be implemented to move in the direction.
도 2는, 본 발명의 일 실시예에 따른 전지 셀 적층 지그에 전지 셀이 정렬되어 적층되는 모습의 일 예를 개략적으로 나타낸 도면이다. 2 is a view schematically showing an example of a state in which battery cells are stacked and stacked in a battery cell stack jig according to an embodiment of the present invention.
도 2를 참조하면, 도 2의 우측에 도시된 전지 셀(10)은 전방향으로 돌출된 전극 탭(t)과 후방향으로 돌출된 전극 탭(t)을 구비하고 있다. 이러한 전지 셀(10)은 도 2의 좌측에 도시된 전지 셀 적층 지그에 정렬된 상태로 적층될 수 있다. 즉, 상술한 바와 같이 제1블록(210) 및 제2블록(220)이 안착부(100) 상에서 이동되어 전지 셀(10)이 정렬될 수 있도록 배치된 다음, 전지 셀(10)들이 제1블록(210) 및 제2블록(220) 사이에 삽입되어 순차적으로 적층될 수 있다. Referring to FIG. 2, the battery cell 10 illustrated on the right side of FIG. 2 includes an electrode tab t protruding forward and an electrode tab t protruding backward. These battery cells 10 may be stacked in a state aligned with the battery cell stack jig shown in the left side of FIG. That is, as described above, the first block 210 and the second block 220 are disposed to be moved on the seating portion 100 so that the battery cells 10 can be aligned, and then the battery cells 10 are firstly arranged. Inserted between the block 210 and the second block 220 may be sequentially stacked.
일 실시예에 의하면, 제1블록 및 제2블록의 배치와 전지 셀의 적층 과정은 다음과 같이 수행될 수 있다. 즉, 먼저 적어도 하나 이상의 전지 셀(10)이 안착부(100) 상에 안착된 다음 제1블록(210)과 제2블록(220)이 전지 셀(10)의 외곽 규격에 맞게 배치된 상태에서, 나머지 전지 셀(10)들이 전지 셀(10)의 외곽 규격에 맞게 배치된 제1블록(210) 및 제2블록(220) 사이에 삽입되어 순차적으로 적층될 수 있다. According to an embodiment, the arrangement of the first block and the second block and the stacking process of the battery cells may be performed as follows. That is, at least one battery cell 10 is first seated on the seating part 100, and then in a state in which the first block 210 and the second block 220 are disposed in accordance with the outer standard of the battery cell 10. In addition, the remaining battery cells 10 may be inserted between the first block 210 and the second block 220 disposed according to the outer standard of the battery cell 10 and sequentially stacked.
다른 실시예에 의하면, 적층할 전지 셀(10)들이 모두 안착부(100) 상에 적당히 안착된 다음 제1블록(210)과 제2블록(220)이 전지 셀(10)의 외곽 규격에 맞도록 배치되면서 전지 셀(10)들을 정렬할 수도 있다.According to another embodiment, all of the battery cells 10 to be stacked are properly seated on the seating part 100, and then the first block 210 and the second block 220 meet the outer specifications of the battery cell 10. May be arranged so that the battery cells 10 may be aligned.
이와 같이, 전지 셀(10)을 정렬하는 제1블록(210) 및/또는 제2블록(220)이 이동가능하도록 구현됨으로써, 다양한 규격의 전지 셀(10)을 적층할 수 있다. 예를 들어, 전지 셀(10)의 외곽의 크기가 8×6인 전지 셀(10)들을 적층하기 위해서는 8×6의 규격에 적합한 전지 셀 적층 지그가 필요하고, 전지 셀(10)의 외곽의 크기가 12×9인 전지 셀(10)들을 적층하기 위해서는 12×9의 규격에 적합한 전지 셀 적층 지그가 필요하다. 따라서, 적층하고자 하는 전지 셀(10)들의 크기에 따라 전지 셀 적층 지그를 별도로 설계하고 제작해야 하는 불편이 존재한다. 그런데, 본 발명에 따르면, 전지 셀(10)을 정렬하는 제1블록(210) 및/또는 제2블록(220)이 이동가능하므로, 다양한 규격의 전지 셀(10)들을 적층하는 것이 가능하다. 즉, 상기의 예에서, 전지 셀(10)의 외곽의 크기가 8×6인 전지 셀(10)들을 적층할 경우에는 8×6의 규격에 적합하도록 제1블록(210) 및/또는 제2블록(220)이 이동하면 되고, 전지 셀(10)의 외곽의 크기가 12×9인 전지 셀(10)들을 적층할 경우에는 12×9의 규격에 적합하도록 제1블록(210) 및/또는 제2블록(220)이 이동하면 된다.As such, since the first block 210 and / or the second block 220 aligning the battery cells 10 are implemented to be movable, the battery cells 10 having various specifications may be stacked. For example, in order to stack the battery cells 10 having an outer size of the battery cell 10 of 8 × 6, a battery cell stack jig conforming to the 8 × 6 standard is required, and In order to stack the battery cells 10 having a size of 12 × 9, a battery cell stack jig conforming to a standard of 12 × 9 is required. Therefore, there is a inconvenience in that the battery cell stacking jig must be separately designed and manufactured according to the size of the battery cells 10 to be stacked. However, according to the present invention, since the first block 210 and / or the second block 220 aligning the battery cells 10 are movable, it is possible to stack the battery cells 10 having various specifications. That is, in the above example, when stacking the battery cells 10 having an outer size of the battery cell 10 of 8 × 6, the first block 210 and / or the second to meet the standard of 8 × 6 The block 220 may be moved, and when stacking the battery cells 10 having an outer size of the battery cell 10 of 12 × 9, the first block 210 and / or conforms to the standard of 12 × 9. The second block 220 may move.
선택적으로, 본 발명에 따른 전지 셀 적층 지그는 전지 셀(10)에 구비된 전극 탭(t)을 기준으로 전지 셀(10)을 정렬하고, 전지 셀(10)들이 순차적으로 적층될 수 있도록 할 수 있다.Optionally, the battery cell stack jig according to the present invention aligns the battery cells 10 based on the electrode tabs t provided in the battery cells 10, and allows the battery cells 10 to be sequentially stacked. Can be.
도 3은, 본 발명의 일 실시예에 따른 전지 셀 적층 지그에 전지 셀이 정렬되어 적층되는 모습의 다른 예를 개략적으로 나타낸 도면이고, 도 4는, 도 3의 정면도이다. 3 is a view schematically showing another example in which battery cells are aligned and stacked on a battery cell stack jig according to an embodiment of the present invention, and FIG. 4 is a front view of FIG. 3.
도 3 및 도 4에 도시된 적층 방법의 일 예는, 도 2와 비교할 때 전지 셀(10)이 전지 셀(10)의 외곽을 기준으로 정렬되는 것이 아니라 전지 셀(10)에 구비된 전극 탭(t)을 기준으로 정렬된다. 즉, 제1블록(210) 및 제2블록(220)이 안착부(100) 상에서 이동되어 전지 셀(10)의 전극 탭(t)이 정렬될 수 있도록 배치되고, 전지 셀(10)에 구비된 전극 탭(t)이 제1블록(210) 및 제2블록(220) 사이에 삽입되어 순차적으로 적층될 수 있다. 일 실시예에 따르면, 먼저 적어도 하나 이상의 전지 셀(10)이 안착부(100) 상에 안착된 다음 제1블록(210)과 제2블록(220)이 전지 셀(10)에 구비된 전극 탭(t)의 외곽 규격에 맞게 배치된 후, 나머지 전지 셀(10)들이 전극 탭(t)의 외곽 규격에 맞게 배치된 제1블록(210) 및 제2블록(220) 사이에 삽입되어 순차적으로 적층될 수 있다. 다른 실시예에 따르면, 적층할 전지 셀(10)들이 모두 안착부(100) 상에 적당히 안착된 다음 제1블록(210)과 제2블록(220)이 전지 셀(10)에 구비된 전극 탭(t)의 규격에 맞도록 배치되면서 전지 셀(10)들을 정렬할 수도 있다.An example of the stacking method illustrated in FIGS. 3 and 4 is that the electrode tabs provided in the battery cells 10 are not aligned with respect to the periphery of the battery cells 10 as compared to FIG. 2. sorted by (t). That is, the first block 210 and the second block 220 are disposed on the mounting part 100 so that the electrode tab t of the battery cell 10 can be aligned, and provided in the battery cell 10. The electrode tab t may be inserted between the first block 210 and the second block 220 and sequentially stacked. According to one embodiment, at least one battery cell 10 is first seated on the seating portion 100, and then an electrode tab in which the first block 210 and the second block 220 are provided in the battery cell 10. After being disposed according to the outer standard of (t), the remaining battery cells 10 are inserted between the first block 210 and the second block 220 disposed according to the outer standard of the electrode tab t and sequentially. Can be stacked. According to another embodiment, all the battery cells 10 to be stacked are properly seated on the seating part 100, and then an electrode tab having the first block 210 and the second block 220 provided in the battery cell 10. The battery cells 10 may be aligned while being disposed to meet the standard of (t).
한편, 전지 셀(10)이 적층되어 제조되는 전극 조립체의 크기는 에너지 밀도와 직접적으로 관계가 있다. 즉, 전극 조립체의 크기가 크면 에너지 밀도가 높고, 전극 조립체의 크기가 작으면 에너지 밀도가 낮다. 따라서, 에너지 밀도를 조절하기 위해 전극 조립체의 크기가 다양하게 변경될 필요가 있다. 그리고, 전극 조립체의 크기는 적층되는 전지 셀(10)의 크기를 조절함으로써 조절될 수 있다. 즉, 전지 셀(10)에 있어서, 전극 탭(t)의 규격이 변경되는 경우보다는 전지 셀(10) 자체 즉, 전지 셀(10)의 외곽의 크기가 변경되는 경우가 많다. 따라서, 전지 셀(10)의 외곽을 기준으로 전지 셀(10)을 정렬하기 보다는 전지 셀(10)에 구비된 전극 탭(t)을 기준으로 전지 셀(10)을 정렬하는 것이 좋다.Meanwhile, the size of the electrode assembly in which the battery cells 10 are stacked is directly related to the energy density. In other words, if the size of the electrode assembly is large, the energy density is high, and if the size of the electrode assembly is small, the energy density is low. Therefore, the size of the electrode assembly needs to be variously changed to adjust the energy density. In addition, the size of the electrode assembly may be adjusted by adjusting the size of the battery cells 10 to be stacked. That is, in the battery cell 10, the size of the battery cell 10 itself, that is, the outer periphery of the battery cell 10 is often changed, rather than the case where the size of the electrode tab t is changed. Therefore, it is preferable to align the battery cells 10 based on the electrode tabs t provided in the battery cells 10 rather than aligning the battery cells 10 with respect to the outside of the battery cells 10.
한편, 제1블록(210) 및 제2블록(220)은 전극 탭(t)의 너비만큼 이격 배치되는 것이 좋다. 즉, 도 3 및 도 4에 도시된 바와 같이, 전극 탭(t)의 너비를 d라고 하고, 제1블록(210)과 제2블록(220) 사이의 거리를 l이라고 할 때, d와 l이 같거나, d가 l보다 미세한 차이로 작은 것이 좋다. 이와 같이 제1블록(210)과 제2블록(220)이 전극 탭(t)의 너비만큼 이격 배치되면 전지 셀(10)의 정렬도가 더욱 향상될 수 있다.Meanwhile, the first block 210 and the second block 220 may be spaced apart by the width of the electrode tab t. That is, as shown in FIGS. 3 and 4, when the width of the electrode tab t is d and the distance between the first block 210 and the second block 220 is l, d and l It may be the same, or d may be smaller than l by a slight difference. As such, when the first block 210 and the second block 220 are spaced apart by the width of the electrode tab t, the alignment degree of the battery cell 10 may be further improved.
일 실시예에 따르면, 전지 셀 정렬부(200)는, 2개일 수 있다. According to one embodiment, the battery cell alignment unit 200 may be two.
